What is a HEX Code?
A HEX code (short for hexadecimal code) is a six-digit alphanumeric combination used to represent colors in web design and digital graphics. It's a compact way to define a color's intensity of red, green, and blue (RGB) light, creating millions of possible shades.
HEX codes typically start with a hashtag (#) followed by six characters, which can be numbers (0-9) or letters (A-F). Each pair of characters represents the intensity of one of the primary colors: red, green, or blue.
Example: #FF0000 (pure red)
Understanding the HEX Color System
The HEX color system is based on the hexadecimal numbering system, which uses 16 symbols: 0-9 and A-F. Each color component (red, green, blue) is represented by two hexadecimal digits, ranging from 00 (no intensity) to FF (maximum intensity).
